Abstract


With the formation of China 's large-scale cascade hydropower stations , as well as the reform of the electricity system gradually deepening and norms , Changwangfenkai bidding grid management model is about to be formed . In this new situation , how to carry out the reservoir optimal scheduling work is placed in front of each power generation company a critical issue . This paper combines the actual operation of the Wujiang River cascade reservoirs , scientific theories and methods of system optimization scheduling problem of the Wujiang River cascade hydropower stations , the objective function of the optimization scheduling and their solutions and to develop a Wujiang River cascade hydropower stations power generation plan used to guide the operation of cascade reservoirs in 2005 . The main research contents and the results achieved in the following areas : (1) discusses the necessity and urgency of carrying out this study , the main content of the technical route ; (2) for the Wujiang River Cascade Hydropower Plants on long-term optimal generation scheduling and planning of power generation characteristics and requirements , the establishment of the Wujiang River cascade hydropower optimal scheduling largest power generation model and cascade accumulator model , and pointed out that the conditions of application of the model ; ( 3) a comprehensive analysis of the domestic and foreign reservoir optimal scheduling for solving a variety of advantages and disadvantages of the method , combined with the actual situation of the Wujiang River cascade hydropower stations , the study proposed for solving the maximum amount of power generation models with hybrid dynamic programming method and system decomposition coordination method for solving the cascade hydropower stations maximum energy storage model distribution method and dynamic search method ; (4) to develop power generation plan of the Wujiang River cascade hydropower stations in 2005 , and using the guidance of cascade hydropower stations have been put into operation scheduling .
